Specification of Letters Patent.

Patented Jan. 17, 1922.

Application filed November 18, 1918. Serial No. 263,052.

To aZZ whom it may concern:

Be it known that I, HENRY J. EnwArns, a subject of the King of GreatBritain and Ireland, residing at Elyria, county of Lorain, and State ofOhio, have invented certain new and useful Improvements inInternal-Combustion Engines, of which I declare the following to be afull, clear, and exact description.

This invention relates to internal combus tion engines and particularlyto a V-type Knight engine wherein there are a plurality of slidingsleeve valves, the object of the invention being to provide improved,simplified, unitary means for accurately operating in proper timedrelation the plurality of sleeve valves. In such V-type engine there isusually provided an eccentric shaft for operating suitable eccentricarms, which in turn control the sleeves, and the object of the presentinvention is to provide a single eccentric shaft for operating theseveral eccentrics for the sleeve valves in both the right hand and lefthand engine of the V- type construction, in order to simplify theconstruction and to condense the same as much as possible. In reducingthe invention to practice to get the correct timing, it was found thatthe location of the eccentric shaft compared with the crank shaft of theengine and the lugs on the sleeves had to be accurately determined andthe arrangement of the parts shown herein represents a practicalembodiment of the invention capable of producing an operative structurewith correct timing of the operation of the valves.

Further objects of this invention relate to the details of constructionhereinafter set forth in the detailed description to follow. Iaccomplish the objects of this invention in one instance by thearrangements shown but it is evident that the same might be variedwithout departing from the fundamental idea of providing a singleeccentric shaft in V-type rlnight motor. One structure constituting anembodiment of the invention. which may be preferred is illustrated inthe accompanying drawing forming a part hereof in which Figure I is alongitudinal sectional view with the crank shaft and eccentrio shown inelevation for the purpose'of clearness. Figure II is a transversesectional view of the engine and Figure III is a plan view of theeccentric shaft detached from the :ncechanismv Referring to thedrawings, the crank casing 10 is shown as supporting a plurality ofcylinders arranged in a V and constituting the right hand engine 11 anda left hand en gine 12. The engine is provided with the usual crankshaft 13 located centrally thereof, as clearly appears from Figure II,while the engine, being of the Knight type, is also provided with theusual sliding sleeves let and 15. The crank shaft 13 is provided at oneend thereof with a gear (not shown) for driving a chain 16. Theprovision of single eccentric shaft driven by the chain 16 andoperatively connected with the several sliding sleeves referred to,constitutes the essential part of my invention and, as shown herein,this eccentric shaft 20 is located sul stantially in vertical alignmentwith the crank shaft 13. The eccentric shaft 20 is illustrated in FigureIII detached from the mechanism and has a plurality of end bear ingsurfaces 21 and 22 with a set of intermediate be'arings 23, as shown.Referring to Figure I it will beseen that the central portion of theengine casing 10 has a plurality of depending brackets 24 to form beanings 24 for each of the bearing surfaces 2 of the eccentric shaft 20.Each of the ends 21 and 22 of the eccentric shaft is supported insuitable bearings 25 and 26. It will be seen that between adjacent pairsof the bearings referred to the shaft 20 is provided with foureccentrics 27. Each of these eccentric surfaces is adapted to receivethe eccentric 28 of the eccentric arm 29, which is connected at the end30 with the lug 31 on the sleeve 14, illustrated in Figure II. It willbe seen that between the end bearing 21 and the bearing 23 there are aplurality of eccentrics, one for each of the sleeve valves of twooppositely disposed cylinders of the right hand and left hand enginesrespectively. The proper location of the several eccentrics 27 from oneend of the shaft 20 to the other has been carefully worked out and whenascertained the proper location of the shaft relative to the lugs on thesleeves, the engine may be constructed accordingly and assembled in themanner indicated.

While I have described my invention in more or less detail, and as beingembodied in certain forms, I do not desire or intend to be limited tothe exact location of the bearings and arrangement of the eccentrics onthe eccentric shaft, or to other limitation 15 side of the crank shaftof said engine a casing provided with bearings to the number of one morethan half the total number of cylinders, said bearings being locatedbetween the sets of cylinders on the 0ppo sitely disposed sides of theengine, a single eccentric shaft mounted in said bearings and adapted tobe operated by the crank shaft of the engine provided with eccentricsconnected to the several sleeves of said engine, a complete set of foureccentrics for two opposed cylinders being located between ad jacentbearings. I

In testimony whereof, I aflix my signature.
